Clavis Mythologiarum

The Key to all Mythologies by the Rev. Edward Casaubon, Rector of Lowick: the work as it might have been left in 1831, with the fifty-nine notebooks it was made from, the Tabulation that marks where the sifting stopped, and the story of how the papers survived.

I could not use it. Do you not see now that I could not submit my soul to yours, by working hopelessly at what I have no belief in—Dorothea?Note found inside the sealed envelope, Warwickshire County Record Office; Middlemarch, Ch. LIV
